ALROSA updates heat and power supply systems at its industrial facilities

16 april 2018
ALROSA, the world leader in diamond mining, is implementing a program for the conversion of autonomous boiler-houses and power plants to alternative fuels. As expected, it will allow ALROSA to reduce operating expenses by more than RUB 5.3 billion over the next 10 years.
In 2018, ALROSA is planning to build a gas boiler-house in Almazny settlement in Mirny district of Yakutia.
Moreover, by the beginning of the year the Company had completed the reconstruction of three boiler houses serving Nyurba Mining and Processing Division, converting their boilers from diesel fuel to oil. In Arylakh settlement of Mirny district ALROSA built a gas boiler house, refusing to operate electric boilers, which allowed to reduce the annual electrical energy consumption by more than 40 million kWh.
Igor Zherdev, Head of ALROSA Production Performance Improvement Department, said, “According to our estimates, conversion of boiler houses and power plants to alternative fuels will reduce the Company’s operating expenses by more than RUB 5.3 billion over the next 10 years.”
In addition, ALROSA has commenced a feasibility study for a promising initiative regarding the gasification of facilities in Udachny Mining and Processing Division and Udachny town. It provides for the replacement of the generation resource (electrical heating) with cheaper natural gas. Should the effectiveness of this project be confirmed, it will be implemented in 2019-2021.
